    摘要： A system that generates short charged particle packets or pulses (e.g., electron packets) without requiring a fast-switching-laser source is described. This system may include a charged particle source that produces a stream of continuous charged particles to propagate along a charged particle path. The system also includes a charged particle deflector positioned in the charged particle path to deflect the stream of continuous charged particles to a set of directions different from the charged particle path. The system additionally includes a series of beam blockers located downstream from the charged particle deflector and spaced from one another in a linear configuration as a beam-blocker grating. This beam-blocker grating can interact with the deflected stream of charged particles and divide the stream of the charged particles into a set of short particle packets. In one embodiment, the charged particles are electrons. The beam blockers can be conductors.

    摘要： A zero power sensor node includes a sensor suite including two or more different types of zero power sensors, particularly including at least two of a zero power PZT-bimorph accelerometer, a zero power PZT-bimorph rotation sensor, a zero power PZT-bimorph magnetic sensor, a zero power PZT-bimorph gyroscope, and a zero power acoustic sensor, which may be a PZT-bimorph acoustic sensor or an resonant cavity, and a near zero power-consuming, multi gate electrostatic switch. The node output can send a wake-up signal to trigger a higher power consuming device.

    摘要： Methods, systems, and devices are disclosed for implementing molecular sensors. In one aspect, an ion-gas sensor device includes a pre-concentration module to collect and concentrate a gas-phase chemical for analysis; a piezoelectric fan to produce an air-flow through acoustic streaming to drive the gas-phase chemical released by the pre-concentration module to one or more downstream modules; an ionizer downstream from the piezoelectric fan to ionize the gas-phase chemical; and a gas sensor downstream from the piezoelectric fan and the ionizer to detect the ionized gas-phase chemical driven by the piezoelectric fan. The piezoelectric fan can include a stack of thin-film layers that includes a thin-film piezoelectric layer. The ion-gas sensor device is made into an ultra-portable package capable of integration with mobile communication devices, such as PDA devices or smart phones.
